🛎️ What Is Rotation?
- A rotation turns a shape around a fixed point called the centre.
- The shape keeps the same size and shape, only its position changes.
🛎️ Rotating Shapes Using Tracing Paper
- Place tracing paper on the shape and mark the centre.
- Turn the paper by the given angle in the correct direction.
🛎️ Rotating Shapes on a Grid
- Draw a line from the centre of rotation to one vertex.
- Turn the line by the given angle, keeping the same distance from the centre.
- Repeat for all vertices and join the points to form the new shape.
🛎️ Describing a Rotation
- Draw perpendicular bisectors of matching points to find the centre of rotation.
- Measure the angle at the centre from the original point to the rotated point.
